Definitions

  • the present invention relates to a lawn-mower according to the preamble of claim 1.
  • Lawn-mowers having grass-collectors in most cases work satisfactorily as long as the grass is dry and does not be stickly.
  • all lawn-mowers known by us having a collector, have some kind of connection, e.g. in the form of a tube between the machine itself and the collector. If the grass is wet and stickly, it will stick to the walls of this connecting member, and may even fill it completely.
  • the connecting member will be completely filled, and since grass is continually being filled from the mower, the grass in the connecting member will be hard-stuffed, which makes it difficult to remove. Even if the connecting member is not stuffed, a quantity of grass will generally stick, which has to be removed manually so as not to block the continuous collecting.
  • the US Patent No. 4 149 362 shows a combined lawn mower and grass collector including a rotary type mower having a rearwardly directed discharge opening and a grass catcher mounted on the mower.
  • the front portion of the catcher, attached to the mower, and the corresponding part of the mower have a planar configuration. This means that the mowed grass have to pass through connecting members in form of said front portion of the catcher and a mower discharge opening before it reaches the catcher itself.
  • the collector should be easy to handle, i.e. easy to attach to the machine and easy to empty.
  • the lawn-mower according to the present invention has a superstructure curved after the radius of the knife, enabling it to connect a grass-collector, having the same curvature, adjacent to the knife system.
  • Fig. 1 shows in side view a lawn-mower having a collector according to the present invention.
  • Fig. 2 is a cross section taken along line A-A in Fig 1.
  • Fig. 3 is a cross section taken along line B-B in Fig. 2 with the collector removed.
  • the lawn-mower according to the present invention is built essentially as an ordinary lawn-mower and has a casing 1, four wheels 3, a handle 4, a knife 5, and a grass-collector 6.
  • the back part of the casing 1 constitutes a curved superstructure 7.
  • a flap 8 is shut down in front of an opening 14 in the back part of the superstructure 7 by means of a spring (not shown).
  • the flap 8 is attached to the superstructure 7 through a hinge 10 and is furthermore provided with a locking means 9 which, if need be, cooperates with corresponding parts of the grass-collector 6.
  • the casing 1 In order to throw the mown grass backwards the casing 1 is provided with a downwardly open passage 11 with an opening 12 mouthing in the opening 14 of the superstructure 7.
  • the front edge 13 of the grass-collector As well as the superstructure 7 of the casing 1 being circular, the front edge 13 of the collector 6 reaches immediately up to the outer turning radius of the knife 5 when the collector 6 is mounted on the lawn-mower.
  • the mown grass is thus thrown from the passage 11 and its opening 12 directly into the grass-collector 6 without first passing any transportation distance e.g. in the form of a tube.
  • the grass will easily stick, especially if it is wet and sticky, and sticking grass must be manually removed, which entails the risk of doing so without first cutting off the machine.
  • the superstucture 7 of the casing 1 has a spring biased flap 8 covering the back opening 14 of the superstructure 7 when the grass-collector 6 is not mounted.
  • the lawn-mower can be used even without the collector 6 being mounted.
